provision of means in the closed air circuit in devices of this type wherebythe amount of air in the system may be changed during transient periods without interfering with r thenormal operation of the apparatus.

These and other objects as Will appear from the following disclosure are secured by means of this invention.

Figure 3 is an end elevational view of the cone shaped member employed in this ar- Figure 4 is a side elevational view of the I apparatus showing the device of this invention associated therewith.

In the treatment of fibers in their preparation'for use in mattresses, cushions and the I: like, it is necessary to break up the fibers from a matted, compact form to a loose, fiulfy con'-.

dition and,at the same time, to remove therefrom all dust and foreign materials such as, vfor instance, seeds in the case ofthose fibers which contain them. One form of apparatus for carrying out these operations is disclosed in my co-pending application Serial No.

"ofithis invention relates to an improvement for use in an apparatus of this type in which .i during the transient periods While the blower "1 through the conduitsystem may be varied as speed ischanging the volume of air flowing ii -Figure =4a-genera1assemblage 'of li'netruments comprising an aeration tank 10, having the inlet conduit sand the outlet conduit 1. 1 rilet eonduit 1' "eiite'ndsfinto an enlarged cylindrical member 3 "and is centered "with res ee't thereto and partially "supported iby means of an annular screen 2 which" completelyehciroles itas' islear rr'onrFigures '1- and 2. Attached to the cylindrical member 3*is "a convergin section 4 *vvli-ieh some with the cylindrical conduit 7 lead-ing to the intake sideo'fthe blowers. The deliveryend of the bloweris conneoted to the' conduit-'9. Mountedwith'i'n the eylindri'calmeihber' and e aced therefromis a conical member'f l whiehjhas its "apex end projecting a short distance into the conduit -1. The *oonioaLmember 5 is sup-- portetl at a number of points by meane'of pins 6 attached to the cylindrical member sand spaoing it'therefrom I The operation-of the'de'vice issuch'that whenever "the blower isp'eed varied sothdt theret of travel of the air" flowi'ngthrough c the conduitsystem changes, the quantity of air in the system'mayohange by anirifiux or emo or fresh air'throu-gh the 'screenmeniher 2. If a provision ofthis nature is not made, the fiberladen air du'e toi'ts inertia piles up o'nfone si de or theoth'er of the blower interupting the 'smooth flow thereof during "trans'i'entperi'od's. Inthe'c'ase of influx thefresh incomingai r contacts with and minglesf with the air "coming from the conduit 1 within the annularspace formed' bythe wall or chamber 3 and tlre 'conical member 5. Asa result the fresh air is mixed with and evenly distributed to the'air already inthe system without interruptin the operation thereof "and without disturbing its proper-operating conditions.

It is, of course, appa'rentthat some changes in the details of cons'truetion and relative arrangement'of 'p'artswill readily occur to those skilled in the art and I do not, therefore, desire to be restricted to the form of the invention used for illustrating the principles thereof, but rather to the scope of the invention as defined below.

What I seek to secure by United States Letters Patent is: I

1. In a machine for treating fibers, the

combination With an aeration tank and a closed circulatory system having a blower therein, of means in said circulatory system for automatically introducing fresh air into the system during periods of blower speed change Without an interruption of the operation thereof.

2. In an apparatus for. treating fibers and I the like, the combination With an aeration tank and a closed circulatory system communlc'ating therewith and having means for creatmg a current of a1r therein, of means for automatically introducing fresh air into the system in response to variations in the velocity ofthe air moving through the sys;

tem.

' 3. In device of thetype described,the

combination of a chamber, ascreen forming one wall of the chamber, a conduit extending therein through sa1d screen, and means in the chamber for deflecting the flow of air, as it leaves said conduit to enter the chamber, tovvards the Walls thereof.

. AL. Ina device of the type described, the combination comprising a cylindrical chamber extending into a conduit, another conduit extending into the otherendof the chamber, a screen encircling said second conduit and forming a Wall for the chamber, and conical means supported Within the chamber and away from the Walls thereof for changing the path of flovv of a gas in fiowing from said second conduit. p

5. In a device of the type described, the combination comprising a cylindrical chamber extending into a conduit, another conduit extending into the'other end of the chamber, a screen encircling said second conduitand forming a Wall for the chamber, anda conical member mounted Within said chamber and having its apex extending a short distance into said second conduit. 6. In a device of the type described, the

combination of a first conduit having an en.-

la'rged portion, a second conduit extending into the enlarged portion and spaced from the Walls thereof, a perforated annular ring encircling said second conduit and'forming a Wall for the open end of the enlarged portion of said first conduit, and a conical member supported Within the enlarged end and having its apex projecting va short distance into the second conduit. 7

In testimony whereof I have hereunto set my hand this 22nd day of March, A. D. 1928.
